[0026] Referring to Figure 1 - Figure 3 , an embodiment of the present utility model provides a gas tank structure for a ring main unit, which includes a load-bearing unit 100 and a sliding and lifting unit 200.

[0027] The load-bearing unit 100 includes a gas tank body 101 and a fixed frame 104 fixedly connected to the upper surface of the gas tank body 101. A guiding air pipe 106 is fixedly connected inside the fixed frame 104. The upper surface of the interruption air valve 209 is fixedly connected with a connecting air pipe 213. The upper surface of the connecting air pipe 213 is fixedly connected with a guiding air pipe 106. The upper surface of the guiding air pipe 106 is fixedly connected with a pressure detection pipe 105. One side of the gas tank body 101 is fixedly connected with a box door 102 through a hinge. An observation window 103 is fixedly connected inside the box door 102;

[0028] The sliding and lifting unit 200 includes a sliding plate 207 slidably connected inside the gas tank body 101 and a rotating ring 202 fixedly connected to one side of the sliding plate 207. A guide rail 211 is fixedly connected inside the gas tank body 101. An electric push rod is fixedly connected inside the guide rail 211, and one end of the electric push rod is fixedly connected with the sliding plate 207. The sliding plate 207 is slidably connected inside the guide rail 211. A partition plate 206 is fixedly connected inside the gas tank body 101. The upper surface of the partition plate 206 is fixedly connected with an interruption air valve 209. A connector 212 is fixedly connected inside the partition plate 206. A first electric telescopic rod 208 is fixedly connected inside the gas tank body 101. A support rod 201 is threadedly connected inside the rotating ring 202. A second electric telescopic rod 205 is fixedly connected to the inner surface of the gas tank body 101. The upper surface of the second electric telescopic rod 205 is fixedly connected with a lifting plate 204. A sliding groove 203 is hollowly arranged inside the gas tank body 101. An L-shaped insertion groove is hollowly arranged inside the lifting plate 204. A clamping plate 210 is fixedly connected to one side of the first electric telescopic rod 208. The sliding plate 207 is slidably connected inside the sliding groove 203. The number of the first electric telescopic rods 208 is several, and several first electric telescopic rods 208 are all centrosymmetric about the center of the sliding plate 207.

[0029] When the device is working properly and the ring main unit needs to be used, first open the box door 102. Use the electric push rod to make the sliding plate 207 slide along the guide rail 211 to the specified position, and place the ring main unit on the upper surface of the sliding plate 207. At this time, rotate the support rod 201 inside the rotating ring 202 to contact the ground. By rotating the support rod 201 inside the rotating ring 202, make the plane where the support rod 201 is located perpendicular to the ground plane, thereby providing stable support for the ring main unit;

[0030] The guiding air pipe 106 and the connecting air pipe 213 guide the gas to the pressure detection pipe 105 to monitor the air pressure in the air box in real time. During the operation of the ring main unit, if it is necessary to adjust the height of some ring main units, it can be achieved by the second electric telescopic rod 205, making the lifting plate 204 rise, thereby adjusting the height of the ring main unit. Further, use the clamping plate 210 to squeeze the base of the ring main unit, and then squeeze the two sides of the base of the ring main unit, thereby fixing the ring main unit. At the same time, the design of the L-shaped insertion groove enables the ring main unit to be lifted to slide smoothly in the sliding groove 203 and perform limit fixing;

[0031] The interruption air valve 209 can control the flow of gas according to the actual situation to ensure the stable air pressure in the air box. When the ring main unit needs to be maintained or repaired, the inside of the air box can be viewed through the observation window 103, which is convenient for the operator to understand the operation state of the device. At the same time, the design of the connector 212 enables the ring main units to be quickly connected and disassembled, improving the maintenance efficiency of the device.
